I took the CT in to get an oil change a few weeks ago and the service tech tells me I also need to change my transfer case oil. I got 16,000 on her and was wanting to know if anyone has had this done yet.
I trust you have the 4WD Chef? Sounds about right. My Ridgeline threw codes for rear transfer oil at about 15k and 35k. I use the Maintenance Minder, it does throw the codes based on how you drive, it is not a set mileage thing. The Ridgeline also has a front case that needed its first change at about 43k miles.
